Support arbitrary whitespace and commas between attributes

[GoogleCodeExporter]

Some time in the Graphviz 2.21.x development cycle, the xdot output changed 
subtly. There is now a space before each comma in the attribute lists of nodes 
and edges, and Canviz isn't robust enough 
to handle that. Canviz should match the regex [\s,]+ in between attributes 
instead of ,\s* as currently.

Input:

digraph G { a }

Output with Graphviz 2.20.2:

digraph G {
    node [label="\N"];
    graph [bb="0,0,54,36",
        _draw_="c 5 -white C 5 -white P 4 0 0 0 36 54 36 54 0 ",
        xdotversion="1.2"];
    a [pos="27,18", width="0.75", height="0.50", _draw_="c 5 -black e 27 18 27 18 ", _ldraw_="F 14.000000 11 -Times-Roman c 5 -black T 27 10 0 5 1 -a "];
}

Output with Graphviz 2.21.20080918.0445:

digraph G {
    node [label="\N"];
    graph [bb="0,0,54,36",
        _draw_="c 5 -white C 5 -white P 4 0 -1 0 36 55 36 55 -1 ",
        xdotversion="1.2"];
    a [pos="27,18" , width="0.75" , height="0.5" , _draw_="c 5 -black e 27 18 27 18 " , _ldraw_="F 14.000000 11 -Times-Roman c 5 -black T 27 10 0 5 1 -a " ];
}
